The lower floor for handling the castings, the elevator floor or support has thereon the main tum- 5 for the packing from the lower floor to the bler or separating cylinder or barrel, into upper fioor, with the conveyer for the packwhich the castings and packing when used ing on the upper floor, and showing also the in connection with annealed castings are dehoppers and spouts for the fine particles and livered or deposited. The castings and packdust of the packing and for the coarse packing are dumped into a delivery hopper or mo ing, and the annealing-pot made up in secspout A, fixed to the second floor and having tions, with the fluid-pressure cylinder for an inclined rear Wall a, a straight front wall a with an 0 enin therein in line with the opening of the main tumbler or separating cylinder or barrel, and a curved end or neck a at the bottom to insure the passing of the castings and packing into the open end of the tumbler or cylinder.

The main tumbler or separating cylinder or barrel B is formed with encircling hoops or rings B around the body, and the body is formed of a series of longitudinal bars 13*. The hoops or rings each have an outer rim 1) and an inner rim b connected by a neck I), forming in effect a double-T construction. The inner rim 5 has inward-projecting brackets or lugs, each having a plate or flange b and a rib or fin 11 The longitudinal bars of the body are each formed with a plate or flange b and a central longitudinal rib b for attachment to the plate or flange b of the depending brackets or lugs of the hoops or rings by bolts 12 or in any other suitable manner. The setting of the longitudinal bars is one which leaves a small space or opening b the full length of the bars and longitudinally of the main tumbler or cylinder.

The encircling hoops or rings or encompassin g bands B act as Wheels or carriers to mount the main tumbler or barrel as a whole, so as to be rotatable, for which purpose the outer rim of each hoop, ring, or band forms a tire to ride on flanged rollers or friction-pulleys B mounted on a shaft B supported in suitable journal boxes or bearings 19 on the frame on which the main tumblerorcylinderis mounted. A shaft 13, with its flanged rollers B is provided on each side of the tumbler or cylinder, and one shaft is provided with a driving-pulley 13 by means of which the shaft on one side can be revolved for the friction rollers or pulleys of the shaft to revolve the main tumbler or cylinder through the travel of the hoops, rings, or bands. The castings and packing deposited in the interior of the tumbler or separating-cylinder will carry the packing removed from the castings the same as in the operation of an ordinary tumbling barrel or cylinder. The packing after it is loosened and separated from the castings is free to fall through the interstices or openings b of the main tumbler or cylinder, and in order to give the packing a descending direction and prevent any part or portion thereof from falling through the side of the openings guide-boards b are provided on each side of the tumbler, as shown in Figs. 3, 4-, and 5.

The main tumbler or separating-cylinder is supported on aframework having,as shown, side sills B supported on posts B with end sills B and is set with a downward inclination toward its delivery end forits rotation to feed the castings to the delivery end of the tumbler or cylinder. The cleaned castings pass from the delivery end and are discharged onto an endless elevator or conveyer 0, running between the side pieces or boards of a frame or trough O and over wheels 0 one at each v1 and 2.

end of the endless elevator or conveyer and its support in frame or side pieces. The endless belt of the elevator or conveyer is provided with straight cleats, buckets, or flights c, by which the castings are caught and'carried upward to be delivered onto the second floor, for which purpose the elevator or conveyer O has an upward inclination, as shown in Figs. 1 and 2. The castings carried by the elevator or conveyer G are deposited into a delivery trough or spout D, having a downward and outwardly inclined bottom (1 and a side board or piece (Z, as shown'in Figs. 1

and 2.

The trough or spout D delivers the castings to an endless conveyerE, for which purpose its delivery end is located above and extends over a trough frame or support F, Within which or between the side pieces of which is a trough or receiver F, supported by the outer frame or side pieces, and the outer frame or side pieces are supported on uprights or standards f, extending up from the second floor or other support,as shown in Figs. The endless conveyer E runs in the trough or receiver F and, as shown, is in the form of a cable, rope, or round belt, having thereon disk or button flights or buckets e at regular intervals apart, by means of which the castings as they are deposited in the trough or receiver F from the delivery trough or spout are caught and carried along the trough or receiver F, so as to be removed therefrom by an operator or workman standing by the side of the trough or receiver or to be discharged therefrom, as hereinafter described.

The cable, rope, or belt of the endless conveyer E runs over pulley or carrying-wheels E at each end of the conveyer. Each wheel E is mounted on a shaft E supported in suitable journal-boxes on standards or posts E Each wheel has an outer rim connected with its center or hub by spokes or arms, and the rim is divided into sections by openings e, one opening in line with each spoke, into IIO which opening the disks or buttons e enter as the wheel is rotated to drive or move the conveyer.

. The castings, as before stated, can be taken from the receiver or trough by an operator or workman and when removed are thrown into a delivery chute or spout G. A number of these chutes or spouts are provided extending through and down from the second door and each having a cover g, so that by raising the cover the operator or workman can successivelydeposit the castings in the several delivery chutes or spouts, using one chute or spout after another. The delivery chutes or spouts are each located over a tumbling barrel or cylinder H, as many tumbling barrels or cylinders being provided as there are chutes or spouts. Each tumbling barrel or cylinder has its body formed in sections, so that one section can be removed and leave a mouth or opening, which when in line with the chute or spout permits the A m Fl castings to be delivered into the tumbling barrel or cylinder from the chute or spout. The several tumbling barrels or cylinders are driven from a common shaft H, having at one end a driving-pulley H and mounted in suitable standards or uprights H Each tumbling barrel or cylinder at one end has a bearing ring or band h, which when the tumbling barrel or cylinder is in use contacts with a friction driving roller or pulley h for rotating the barrel or cylinder. Each tumbling barrel or cylinder is mounted in suitable journal boxes or bearings at each end, and the journal box or bearing for the end of each tumbling barrel or cylinder having thereon the friction driving ring or band h is movable, so that it can be moved outward and disengage the friction band or rim from the friction roller or pulley and stop the revolving of the tumbling barrel or cylinder. The castings are given a final tumbling in the tumbling barrels or cylinders H to complete their cleaning, and when the cleaning is completed the castings are removed from the barrel or cylinder and can be taken away for use or otherwise.

The packing separated from the castings by the action of the main tumbler or separating-cylinder sifts through the interstices or openings 11 and drops onto an endless conveyer I, the conveyer being of a width sufficient to receive the packing deposited from the tumbler or cylinder. veyer I is mounted upon cylinders or drivingrollers I at each end thereof, and the cylinders or rollers are mounted on driving-shafts 1 the shaft at one end being supported in suitable boxes i and at the other end in standards or uprights 'i in the construction shown. The loose packing deposited on the conveyer I from the main tumbler or separating-cylinder is carried toward the delivery end of the conveyer, which, as shown, is in a lower plane than theopposite end, and from such delivery end of the conveyer the loose packing is deposited onto the upper face of an endless traveling belt or conveyer J, passing over a retaining-boardj, a similar board being on the opposite side of the traveling belt or con.

veyer J. The traveling belt or conveyer J has a fast travel and has an upward inclination from its receiving end to its delivery end, as shown, which inclination by reason of the fast traveling of the belt further divides and separates the packing, and the packing is re- The endless con-.

and inward inclination, as shown in Figs. 2 and 3, with its delivery end in position to discharge the loose packing onto a perforated plate Z, which acts as a sieve by which the fine material and dust are sifted into a hopper L and carried bya discharge-spoutL to the point for its deposit. The sieve or perforated plate Z is located between the sides or walls of an outer frame or support M in the bottom of an inner trough or receiver N. The outer frame or support M carries the trough or receiver N and is supported on posts or uprights m and cross-pieces m, and extending up from the cross-pieces m are posts or uprights m having cross-pieces m which carry the side pieces of an upper frame or support M. The trough or receiver N is made up of sections, and one section a between each upright or post is hinged by a suitable pin or pivot 01', so as to have a free end that can drop, and connected with this free end is a cord n running up over a pulley n and having attached to its end a weight M, which permits the pivoted or drop section n to fall down at its free end, leaving an opening in the trough or receiver and furnishing a spout for discharging the coarse packing. The spout is returned and held in normal position by the cord and weight to form a continuous receiver or trough M, except when one section a is dropped, and the dropping of each section a is permitted by an opening m in the sides of the outer frame or support in line with the section.

An endless conveyer 0, having thereon disk or button flights 0 similar to the conveyer E, runs in the trough or receiver N and moves the packing delivered from the spout L in the trough or receiver N, and in such movement as the packing passes over the perforated plate or sieveZ the fine dust and particles will be sifted out and pass into the hopper L, and the coarse packing will be carried over the perforated plate or sieve to pass through the trough or receiver N until a dropped section n of such receiver or trough is reached, when the coarse packing will be discharged at the opening formed by the dropped section. The cable, rope, or belt for the endless conveyer 0 runs over a pulley or wheel 0 at each end. The pulleys or wheels 0 have a similar construction to the pulleys or wheels E, each having openings 0 in its rim for the disk or button flights corresponding to the openings 6 of the rim of the pulleys or wheels E and for the same purpose.

A hopper P is located beneath each dropsection n of the trough or receiver N, into which hopper when a drop-section is down, as shown by the dotted lines in Fig. 2, the coarse packing will be deposited, and from the hopper the packing is discharged through 1 charged into the pots, as shown, for one of the pipes P in Fig. 2. I

The annealing-pots Q for the castings are made up in sections or divisions to facilitate handling, and each section has in its opposite side Walls a hole or opening q to receive the endsr of thelifting and carrying tongs orgrappler R, as shown in Fig. 2, so that by engaging the tongs or grappler with a section the section or division can be raised from the next succeeding section or division and be carried bodily over the receiving and delivering hopper or spoutA for discharging its contents into the hopper or spout, as shown in Figs. 2 and 3. The sections or divisions composing the pot as a whole are mounted on abase Q in the arrangement shown, which base has openings below its top plate for the admission of a pick-up or lifter,which may be the pick-up or lifterof the arm or boom of an overhead traveling crane, (notshown and forming no part of the present invention,) by which the'pot as a whole can be readily handled. The forming of the pot in sections or divisions and mounting the sections or divisions on a base facilitates the handling of the pot as a whole, as each of its sections or divisions can be separately and independently handled with great ease and rapidity.

The tongs or grappler R is connected by a hanger or cross-head s with a piston-rod s of a fluid-pressure cylinder S, which cylinder is suspended by an eye orswivel s from hangers or loops tidepending from axles t,having carrying-wheels t and running on a track T,which track, as shown, is formed by two I-beams beneaththe fioor,but may be otherwise formed. The fluid-pressure cylinder receives pressure through the pipe U from a compressedair reservoir or other source of supply, and the pressure is controlled by a suitable valve operated by a handle or lever u. The admis sion of fluid-pressure into the cylinder below the piston raises the piston-rod and the tongs or grappler to be engaged with a section of the pot, and when engaged further applicacation of fluid-pressure lifts the caught section or division free from the next succeeding section or division, and the section or division so lifted can be carried over the receiving hopper or spout A by the truck or carriage running on the track T, and when in position the pot section or division can be.

knocked or otherwise operated upon to discharge its contents.

An I-beam V, having thereon a rail n, and forming one side of a runway for an overhead traveling crane, is shown in Fig. 3, and an end of a main frame V, having carrying-wheels 1;, which run on the track, is also shown. These parts indicate the position and location of an overhead traveling crane for use in connection with the present invention in placing the filled pots in the annealing-oven, removing the pots from the oven when the castings are annealed, and depositing the pots on the floor or support to have the sections or divisions lifted one by one, and the contents discharged or emptied to pass into the main tumbler or separating-cylinder.

The operation is as follows: The pot of annealed castings is placed on the second floor or support in a position adjacent to the feed hopper or chute A and accessible to the traveling tongs or grappler. The first section or division of the pot is caught by the tongs or grappler, which have been raised into position for the purpose by thefiuid-pressure cylinder and brought over the top of the pot. The caught section or division is raised clear of the remaining sections by operating the fluid-pressure cylinder to raise its piston-rod, and the section or division is then brought over the feed hopper or chute by traveling the truck or carriage of the fluid-pressure cylinder on its track, and the contents of the pot-section are emptied into the feed hopper or chute. The remaining sections or divisions of the pot are successively taken by the tongs or grappler and carried to the feed hopper or chute and discharged, and this operation is continued until all the pots containing the annealed castings have been emptied. The emptied sections or divisions are thrown to one side to be again filled and used. The pot is filled by placing a lower section on the stand or support, filling it with the castings, and discharging the packing thereinto from the packing-spout. The pot is built up by placing one section or division thereof on top of the other as a section or division is filled and packed, and when a pot is completely filled and packed it is to be removed and placed in the annealing-oven, as usual. The construction of the pot in sections or divisions renders the handling thereof more expeditious and easy, both in filling and emptying. The discharged castings and packing from a pot section or division pass through the feed hopper or chute and into the receiving end of the revolving tumbler or separating cylinder, and by the action of such tumbler or cylinder as the castings pass from the receiving end to the delivery end the packing will be separated from the castings and the castings will be discharged at the delivery end practically clear of the packing. The discharged castings pass onto the endless conveyer or elevator O and are discharged therefrom into the delivery tube or spout D to enter the trough or receiver F and be carried along in the trough or receiver by the endless conveyer E, having the disk or button flights thereon, for the castings as they are carried along to be caught by the operator or Workman,removed by hand, and dropped into the hoppers or chutes G on one side or the other of the endless conveyer to pass into the tumbler-barrels H for the final cleaning, ready for use. The separated and loosened packing discharges through the interstices or spaces in the body of the main tumbler or separating-cylinder onto the conveyer I :and is carried by such conveyor and discharged onto the endless traveling belt or conveyer J, to be discharged therefrom and taken by the pockets of the endless elevator or conveyor K, and discharged onto the spout L, to pass down the spout into the trough or receiver N, to be carried along in such receiver or trough by the action of the endless conveyer and its disk or button flights, passing over the perforated disk or sieve at the receiving end of the trough or receiver for the fine dust and particles to pass into the hopper L and be discharged through the pipe L while the coarse packing is carried along in the trough or receiver and discharged therefrom by dropping a movable section over a hopper P for the packing to enter the hopper and its discharge-pipe P for use again.

It will thus be seen that the separating of the packing from the castings is automatically performed in the main tumbler or separatingcylinder and that the castings are carried through the tumbler or cylinder and discharged, while the packing is discharged through the body of the tumbler or cylinder, thus making a clean and distinct line of separation between the castings and the packing in the removal of each. The castings after the first cleaning and the removal of the packing therefrom are automatically carried to a point where they can be caught and delivered for the final act of cleaning. The packing is carried to a point where it can be deposited for use again and in the passage have the fine particles and dust removed, leaving the coarse packing in shape for use. The entire operation of separating the castings and the packing and separating the fine particles and dust from the coarse packing is thus rendered automatic from the start to the finish. The entire operation, with the exception of emptying the filled pot and removing the castings and filling the pots, is automatic throughout. V

It will be understood that While the invention is described for use in connection with annealed castings it can be used and is intended to be used for cleaning other castings from molding-sand and other material, which result is accomplished by depositing the castings in the main tumbler or separating-cylinder to remove the sand and to discharge the sand and castings, as herein described, for the removal of the packing and discharge of the castings and packing.
